Rolex Sea-DWELLER Triple Six Ref 16660 Full Set 1988

Rolex Sea-Dweller ref 16660 "Triple Six" was produced for a little over a decade between 1978 and 1989. It replaced the vintage ref. 1665, bringing with it a sapphire crystal, increased water resistance, and a higher-beat movement. Depending on the reference, it will also have either painted indices or modern white gold-trimmed indices. The example you see here is the latter. With the release of ref. 16660, the bezel was upgraded to a uni-directional mounting, and the Helium Escape Valve is larger. This Rolex is an integral part of the collection's history.
